    摘要: A fiber optic phased array and control method are provided for controllably adjusting the phase and amplitude of the optical signals emitted by a plurality of fiber optic amplifiers to compensate for atmospheric turbulence. The fiber optic phased array also includes a sensor assembly for detecting: (i) the phase of the optical signals that are emitted by the fiber optic amplifiers, and (ii) both the phase and the amplitude of the optical signals that have been reflected by the target. The fiber optic phased array also includes phase modulators and a gain adjustment mechanism for altering the phase and the amplitude of the optical signals propagating along the fiber optic amplifiers to compensate for modifications in the phase and amplitude that will be introduced by atmospheric turbulence. Among other things, the amplitude control of the optical signals is not adversely effected by intensity nulls in the reflected wavefront.

    摘要: The system contains a plurality of sensors outputting sensor data. A processor is in communication with the sensors to receive the sensor data. A logic system is in communication with the processor. The logic system evaluates a likelihood of a plurality of hypotheses, generates a representation of the likelihood of the plurality of hypotheses in a coordinate system, and connects trajectories between a plurality of discrete hypothesis aspects of the plurality of hypotheses. An output of the processor provides at least one likely outcome and a confidence level for each of the likely outcomes. At least one likely outcome is selected based on contours of the representation of the likelihood to of the plurality of hypotheses in the coordinate system.

    摘要: An optical field sensing system and an associated method are provided that are tolerant of scintillation. The system includes a wavefront sensor that measures gradients across a wavefront at a first resolution defined by the subapertures of the wavefront sensor. The system also includes an intensity sensor that measures the intensity across the wavefront at a higher resolution. The system further includes a wavefront processor that determines respective phases across the wavefront. In addition to the gradients and the intensity measurements, the wavefront processor may determine the respective phases based also upon the noise affiliated with the measurements. In this regard, the wavefront processor may determine the respective phases across the wavefront at least partially based upon the gradients as adjusted by weights that are based upon the intensity measured by the intensity sensor and are influenced by evidence of scintillation.
